This does not mean that the weakest males dont mate, they just get picked last by the rest of the females and, over time, the weak males genetics fade out of the species entirely. This is what Darwin called survival of the fittest, the strong males with the most potential will pass on their genes and the weak ones will not, making sure to preserve the integrity of the species. Some animals, for example the Peacock, will dance for the female Peafowls displaying an array of colored eyes, the brighter and prettier the eyes on the Peacocks feathers the healthier the bird is and is more apt to mate (Power point).
